Product Overview

Kraft paper valve bags are specialized high-end packaging products designed for the industrial powder sector. They are made from multiple layers of premium pure wood pulp kraft paper combined with a square bottom valve structure, making them compatible with fully automatic filling equipment.

These bags are primarily used for packaging dry ultrafine materials such as carbon black, white carbon black, silica, rubber additives, chemical powders, and building material powders. Their sturdy bag shape allows for neat stacking, and they possess high strength to resist impact and compression.

With these features, kraft paper valve bags effectively address common industry challenges including bulging during filling, outer layer powder leakage, powder moisture absorption, damage during transportation, and powder seepage during storage. As a result, they have become the mainstream packaging solution for powder factories involved in export, mass production, and long-term storage.

Key Features
Industry-Leading Powder Leakage Prevention

Specifically optimized for ultra-fine powders, this product employs a unique three-layer staggered perforation process to replace the traditional four-layer perforation. This design ensures smooth air ventilation without causing bulging, effectively preventing powder leakage from the paper layer seams.

High Strength & Durability

Made from high-toughness virgin kraft paper with multi-layer composite forming, the material boasts strong tensile strength, tear resistance, and compression durability. It withstands long-distance transportation and multi-layer stacking without easily breaking.

Breathable Pressure Relief

Featuring a precise micro-perforation staggered air release design, the packaging rapidly expels air during filling, keeping the bag flat without inflation. This results in neat and beautiful stacking, ideal for high-speed automated filling lines.

Moisture Protection

When paired with a high-strength PE inner liner, the packaging provides excellent sealing that effectively blocks air and moisture. This prevents moisture absorption and clumping of white carbon black and chemical powders.

Automatic Sealing

The valve adopts a self-locking structure that automatically seals upon completion of filling. This feature prevents fine powder dust from dispersing and material spillage, keeping the workshop environment clean and dust-free.

Environmental Compliance

The packaging is odorless, pollution-free, recyclable, and biodegradable. It meets both domestic and international industrial packaging environmental standards, making it well-suited for cross-border export orders.

High-Definition Printing

Supporting multi-color high-definition printing with precise color matching and no fading, the packaging effectively showcases brand image and improves the product's overall market appeal.

Technical Specifications
Material Standards

The product is made from high-quality, full wood pulp, stretch-thickened kraft paper. The paper surface is smooth, free from oil stains, holes, or cracks. It can be constructed in double-layer, triple-layer, or four-layer structures. Additionally, an optional PE inner film laminating is available, which is firmly bonded without peeling or delamination.

Process and Structural Standards

The bag features a square pasted bottom formed integrally with reinforced weight-bearing capacity to ensure uniform stress distribution. The valve mouth is neat with moderate tightness, compatible with fully automatic and semi-automatic filling equipment, preventing machine jams and material leakage. Dimension deviations are strictly controlled within ±5mm.

Core Performance Indicators
Performance Parameter Description
Tensile Strength The multi-layer paper composite provides uniform tensile force, preventing tears during full-load stacking, handling, and transportation.
Breathability Misaligned micro-holes allow quick air release, avoiding inflation and deformation during filling.
Sealing Performance The valve self-seals effectively to prevent powder leakage and dust emission, even with ultra-fine powders.
Moisture Resistance The inner film blocks water vapor, effectively preventing powder moisture absorption and caking.
Impact Resistance Resistant to drops and compression, ensuring minimal damage during express and full-truck logistics.
Anti-Static Properties (Optional) Meets anti-static requirements for carbon black powder filling.
Appearance Quality Requirements

The bag body must be clean without wrinkles, damage, or bubbles and delamination. Printing should be clear with no ghosting or blurring. The bottom, sides, and valve mouth must be free from cracks or burrs. Each batch undergoes full inspection to ensure consistent and stable quality.

Standard Specifications

Common weight capacities include 10kg, 15kg, 20kg, 25kg, 40kg, and 50kg. The mainstream industrial powder standard is 25kg, and custom non-standard sizes are supported upon request.

Industry Applications
Carbon Black Industry

Dedicated packaging solutions for various types of carbon black, including rubber carbon black, pigment carbon black, conductive carbon black, and cracked regenerated carbon black. Supports anti-static and anti-black powder penetration technologies.

White Carbon Black / Silica Industry

Optimized packaging for both precipitated and vapor-phase white carbon black featuring staggered perforations to prevent powder leakage, seepage, and moisture-induced caking.

Rubber Chemical Powder

Packaging solutions for dry powders in the rubber chemical sector, including rubber additives, zinc oxide, kaolin, filler powders, resin powders, and pigment powders.

Construction Powder Industry

Packaging for construction powders such as putty powder, dry mortar, tile adhesives, gypsum powder, and cement providing stable stacking and strong load-bearing capacity.

Food and Feed Powder

Packaging for starch, food additives, and feed carrier powders, with options to use food-grade materials to ensure safety and compliance.

Automated Factory Production

Compatible with fully automated filling lines, supporting high-speed filling without bag jams or bloating, thus improving production efficiency.
